To all whom i2 may concern.-

lie it known that l, Josnrn E. PERRAULT,

e eitizen of thelinited States, residing at Wslthnrn, in the county ofMiddlesex end .etete of Massachusetts, have invented new and usefulimprovements in Machines for iictting Rivets, of which the following isnspecification.

This invention relates to machines for setting rivets or the like inleather or other sheet material.

The Object of the invention is to provide an improved means for guidingthe rivet from the raceway to the carrier or holder in which it heldprior to being driven in the stock by a suitable driver. in machines ofthis class in which rivets or the like are employed which are fed from ahopper down a, raceway to a. cerrier or other receptacle in which the grivct is placed before being driven, the rivet very hitble, in passingfrom the raceway to said carrier to tip over and enter the carrier withthe shank of the rivet projecting upwardly instead of downwardly as isdesired. This is especially liable to occur when the rivet has a. 1&1 ehead and short shank and it one of the ciscts of this invention toprovials device which shell prevent the rivet from tipping over, ashereinhefore set and. to hoirl the same in correct position to enter theeerrier from the raceway with the bend uppermost and. leave the same insaid senior in proper'pcsition to be driven into the l: by the driver.

The slide 4-1 hes a. "if-shaped slot 42 extending transverselytherescross and a. reciprocatory motion is imparted to said slide by aspring arm 43, the lower end of which projects into a slot 44in theslide 41, the upper end of said spring arm being fastened to the lowerend of it lever 45 pivoted at 46 to the frame of the machine, the upperarm of said lever 47 bye spring 48. A rocking motion is imported to thelever by suitable mechanism, thus importing a rocking motion to thelever 45 and a rociprocntory motion to the slide .41. As the rivetsdescend the upper pert 32 of the raceway 31, the lowermost rivet in saidupper part is carried by the slide 41. from seid upper part intoulincinent with the groove 35 m the foot 34. and sliding down saidgroove 12 sses to the The carrier 256 consists of two side "notes 49,49, each provided in its upper end with o. semi-annular groove ll: toreceive the head oi. the rivet alter it has passed from the racellmnoeth said semi- 49, is is is, is

Thecarrier slide 5 is adopted to slide in ways formed in the head of theframe and named np- Wnrdlv by c. spiral spring 57, the lower end ofwhich is fastened to a screw to said carrier slide, the upper end ofsold spring; no-- ing fastened by screw 59 to the head The material 60into which the rivet is lo be clenched is supported upon so anvil .51which, in turn, is sdjustebly supported noon an arm 62 forming s portionof the frame 20.-

A guide-finger 63 is pivoted at 64 to the carrier slide 54:. The inneredge 65 of the finger 63 is inclined at an angle, at 6'6, to the driver23 and bears against the lower end of said driver, as will be seen inFig. 6, said inner edgebeinn' held preferably in contact with. saiddriver by a. spiral spring 67, one end he olsto's the plates 1 .0 J,said L slide 5- it will he noted that the guide- 'lingcr (-33 is locatedin a slot or groove 69 exlcnding longitudinally of the slide 54 and nout of the inner face thereof. It "a: seen that as the rivets 29 descendthe lower portion 34 of the raceway and pass to the rivet carrier sothey are very liable to tip and enter said carrier in an inverted orpartly" invcrted position. as hereinbefore set forth. This is entirelyobviated by the finger 63, the lower end of which is located in theexact position to allow the rivet to slide freely from the lower part ofthe raceway into the carrier, but will prevent the same from ti pingover by reason of the lowermost end 0 said linger touching the top ofthe head of the rivet as it is passing from the raceway to the carrierand thus guiding it and keeping it in correct position to finally landthe head uppermost in the groove 50 in readiness to be driven, ashereinafter described.

In feeding rivets of diil'erent sizes or forms it becomes necessary toadjust the guidelinger 63 so that the lower end thereof will approachthe lower end of the groove 35 more neorly 'or may be carried fartheraway therefrom in order to correctly guide the rivets, as set forth. Toaccomplish this sch, justinent of the gnide-fingcr a variety of meansmay be employed without departing from the spirit of my invention. Onevery simple means is to lnnit the upward movement of the driver-slide 21and driver 23 by limiting the downward movement of the rear end of thelever 24 which can be conveniently accomplished by means of thestopscrcw 28 (Fig. 1). While I. have illustrated and described thisperticnlor embodiment of my invention constructed with. a guide-fingerhaving on inclined inner edge .fifibeering against the lower end of thedriver 23, it is evident that this inclined or coin-she. ed sur face,mean of which theguidefinger is actuated and its position with relationto the rivets regulated, may be located at on desir I able poi-time. ofthe gnide-finger 63 on that it is not necessary that said inclinedportion snould hove contact with the driver itself.

The general operation of the mechanism licreinhefore s eci'ficollydescribed end illns tinted in the orswings in Figehlt to 13 is asfollows: The rivets are fed from the hopper- 30 to the upper part 32 ofthe i'scewey 31 by any of the well known means for this urpose,8i'1(lSll(l1l1g(l()WXl saidnp or art 0 the raceway in the groove 40 heowerniost its ste eos reeks proper 22'. and the lower end of hi; therivet :s-d pushes said with the i not the notion yer of the 1 t the in.terinl 6O it open the en- .z-kt this point in the ere opera-Jnivorriin, of the ear end as the more: forced rivet is apartsntlidownwardly rrvet they:v driven 1nd clenched upon the l in Fig. FW'nen the tor releases the treadle the different ill at .me the relativepositions illus- Figs. 2 and 3. l
